Benefits of technology

The present invention provides a tire temperature and tire pressure wireless sensing device that can directly detect the gas in the tire and the pressure and temperature of the gas. The device includes a sensing module that is connected to the air-intake through hole on the bottom seat, and a valve body is engaged with the air-intake through hole, allowing the device to directly detect the gas discharged from the valve body and the gas temperature and pressure. The device also includes a transmission antenna that is disposed in the antenna slot and is not connected with the battery and wheels, preventing signal attenuation. The invention also utilizes a semi-circular sidewall on the top of the fixed seat and a battery holder with conductive elements for easy battery replacement, and a bottom seat engaged with an insulation theft-proof element and sealing metal spacer to prevent leakage and theft.

Problems solved by technology

The drawback of above tire temperature and tire pressure wireless sensing device includes: for the tire temperature and tire pressure wireless sensing device, a metal connection terminal is welded on the circuit board and the circuit board which is pressed-fit to cause the metal connection terminal that is electrically connected with the housing.
The wireless signal will be attenuated and the poor contact of the metal connection terminal during the operation.
Secondly, when the sensing device is disposed on the top of the circuit board, and the air-intake through hole is disposed on air-intake seat which is disposed on the bottom of the circuit board, the gas should be passed through the circuit board to be detected by the sensing device, such that the detection data is not to be detected in instant and is not accurate.
When the battery is replaced, the two battery springs are need to switch by the sharp object, such that the replacement of the battery is not convenient for user, and the battery or two battery springs will be damaged, deformed or the poor electrical contact is generated.

first embodiment

[0018]With reference to the drawings and in particular to FIG. 1 to FIG. 4, a structure of a tire temperature and a tire pressure wireless sensing device is shown. The tire temperature and tire pressure wireless sensing device is engaged with an air-intake mouth of the wheel to sense gas temperature and pressure inside the wheel to obtain the usage condition of the tire to increase the drive safety. The tire temperature and tire pressure wireless sensing device includes a housing 10, a valve body 20, a power supply module 30, a circuit board 40 and a transmission antenna 50.

[0019]The housing 10 is engaged with the air-intake mouth (not shown), which includes a fixed seat 11, a bottom seat 12 with a first recess 122 and a cap 13 with a second recess 131. The fixed seat 11 is made by plastic injection molding. The bottom side of the fixed seat 11 includes a circular sidewall and the circular sidewall is engaged with the bottom seat 12 to form an air chamber 15. In this embodiment, the...

second embodiment

[0025]With reference to the drawings and in particular to FIG. 5 to FIG. 8, a structure of a tire temperature and a tire pressure wireless sensing device is shown. The tire temperature and tire pressure wireless sensing device includes a housing 10, a valve body 20, a power supply module 30, a circuit board 40 and a transmission antenna 50.

[0026]The housing 10 includes a fixed seat 11, a bottom seat 12 with a first recess 122 and a cap 13 with a second recess 131. The fixed seat 11 is made by the plastic injection molding. The bottom side of the fixed seat 11 includes a circular sidewall which is engaged with the bottom seat 12 to form an air chamber 15 therein. In this embodiment, the bottom side of the fixed seat 11 includes a corresponding recess 114 that is disposed in the circular sidewall, in which the outside of the circular sidewall includes an outer thread, and the top side of the bottom seat 12 includes a first recess 122. The inner wall of the first recess 122 includes an...

Abstract

A tire temperature and tire pressure wireless sensing device is provided, which includes a housing, a valve body, a power supply module, a circuit board and a transmission antenna. The power supply module is disposed on the fixed seat of the housing, and the circuit board includes a wireless transmission module and a sensing module thereon. The sensing module is disposed corresponding to an air-intake through hole of the bottom seat of the housing. The valve body is engaged with the air-intake through hole and one end of the transmission antenna is disposed in an antenna slot.

Description

FIELD OF THE INVENTION[0001]The present invention relates to a tire temperature and tire pressure sensing device, and in particular to a tire temperature and tire pressure sensing device for detecting the instant and accurate gas temperature and gas pressure, emitting the effective wireless signal and preventing the signal attenuation and is suitable for an air-intake mouth of all kinds of wheel.BACKGROUND OF THE INVENTION[0002]The conventional tire temperature and tire pressure wireless sensing device includes an air-intake device, a bidirectional sleeves and a cap. The air-intake device includes an in-take seat. One end of the intake seat is connected with an intake mouth of wheel. The bidirectional sleeves include a separation part, in which a first connection part and a second connection part are disposed two opposite ends of the separation part respectively. The first connection part is engaged with another end of the air-intake seat to form an air chamber which used to accommo...
